"Francis' plane touched down at Amman's Queen Alia International Airport, where he was met by an honor guard, Catholic leaders and Prince Ghazi bin Mohammed, the king's chief adviser for religious and cultural affairs. He immediately headed to the king's palace in a simple, four-door sedan, a group of motorcycles riding alongside him. Small groups of people waving Jordanian and Vatican flags cheered him as he passed.

"At the palace, Francis met with Abdullah, Queen Rania and their children. In his palace speech, Francis said Jordan's "generous welcome" to Syrian refugees warranted international appreciation and support."

Of course, the big days for Francis are upcoming. He's expected to visit a refugee camp in the West Bank on Sunday and then he will head to Jerusalem on Monday. He'll pray at the Western Wall and visit the Holocaust memorial at Yad Vashem.

As our friend Greg Myre over at Parallels explains, Francis becomes only the fourth pope to visit the Holy Land. This is a rather modern tradition, started by Paul VI in 1964. That trip was followed by Pope John Paul II in 2000 and Pope Benedict in 2009.

Now, it's Pope Francis' turn.

The BBC's Jeremy Bowen says Francis is saying this trip is about religion, "officially marking the fiftieth anniversary of a visit by Pope Paul VI 50 years ago."

But like most things in the Middle East, there is inevitably politics mixed in.

The pope, for example, will leave Jordan and land in the West Bank. As the AP explains, he will the first pope to land in the West Bank, rather than Tel Aviv. The move is considered a "nod by the Vatican to the 'Palestinian state.' "
